Ok,so here's my problem.I'm loading Precisions' 1 1/8 buffered load and had to drop to 1 1/16 to get the stack height right. These things pattern great at 40 yards couldn't ask for anything better. However the wads are breaking in half at the crush section.It's not happening during loading but when firing. When I use them in Hodgdons 1 oz.recipe they hold up fine. The wads are a very dark Royal blue instead of a powder blue. Anybody have any idea what's going on. |

The wads are doing their job.
What chokes are in the gun?
If removable, try a more open choke tube and see
if the wads still separate.
You have you patterned this load, and it does what you want it to do, GOOD
Mike
p.s. the only issue here is re-using the wads like we used to do overseas when components were hard to get
p.s.s. you may be at the max limit of pressure and thrust for this wad,
maybe it will be better when it is colder. Have you put some in the freezer, then igloo, and then shot them to give that a try? |

The guns a prewar Ithaca 37R with a poly on it. I refurbished it a few months ago and it has become my favorite gun. I'm in the process of patterning all settings with both lead and Bismuth. To steal one of your favorite sayings "WHAT FUN". |

Are you using buffer with the 1 oz. load?
Can you see the buffer when you are ready to crimp?
Is the Hodgdon load bufferfd? |

Yes, WHAT FUN!
Was on the right track, but now know more
I would suggest that the pressure is still up on this load
when the wad expands a bit in the polychoke and then is
torn on the trip through the choke.
I see no harm here and the heavier load is making better
use of the powder for a longer burn.
Slow burning powder?

The buffered load is Remington hull,primer and wad. 24.8 grns of Blue Dot and 1 1/16 oz of shot. 12 grns. PSB buffer and a TS over the shot. When I add buffer I tap until the shot just starts to show then put the over shot TS in and crimp. Oh and as always I put about 10 pounds of pressure when I seat the wad. The other load is Remington hull and primer. Remington wad and 18 grns of Universal with 1 oz of shot no buffer. Both loads are just north of 11,000 according to the books. |

The non buffered load is a lot easier on the wad. The increased friction raises the chamber pressure and crushes the compressible section a lot more than it will on the non, buffered load.
Use more wad pressure on the buffered load and vibrate, don't tap in the PSB and the whole 1 1/8 oz. should fit. It will be tight. |
